Im at the point where Im getting ready to put a roof on my "awning" in
the back yard. Its a 16' x 16' freestandinging gizmo that will cover
my welding Stuff, a place to work on vehicles, and so forth. Lots of
similar units around here are flat roofed, but as it appears that we
may be getting some rain for the next couple years, Id like to put a
small slope on it. How much slope should I put in a 8' span, just to
get rid of rain water? 4" 3"?

My shop is 1/4" per foot. I water leveled it and subtracted 3.75" 15'
away. Make it a little more if its not really flat , mine is two
layers of 3/4 plywood.
